Adults of Clinostomum marginatum freshly collected from a heron, Ardea herodias, were examined using transmission electron microscopy. Specimens from the mouth of the bird were encrusted with bacteria that were not removed by washing unless the saline contained antibiotics. There was no evidence that the attached bacteria were damaging to the trematode tegument. Three species of Gram-negative bacteria were isolated from the worm surfaces and identified; Achromobacter sp. was present in pure culture on 4 of 6 original cultures and in mixed culture with Edwardsiella tarda and Enterobacter agglomerans in 2 cultures. These species and 3 unidentified species of bacteria were isolated from the oral epithelium of the heron. Microorganisms were not seen attached to the surfaces of worms recovered from the esophagus. Because E. tarda and E. agglomerans were the only species isolated from the heron esophagus, the intimate bacterial-worm association in the heron mouth may be due specifically to Achromobacter sp.
对刚从一只苍鹭（苍鹭属）体内采集的边缘斜睾吸虫成虫进行了透射电子显微镜检查。从鸟嘴采集的标本表面附着有细菌，除非盐水中含有抗生素，否则水洗无法去除这些细菌。没有证据表明附着的细菌会对吸虫的体表造成损害。从虫体表面分离并鉴定出三种革兰氏阴性菌；无色杆菌属在6个原始培养物中的4个中以纯培养形式存在，在另外2个培养物中与迟缓爱德华氏菌和聚团肠杆菌混合培养。这些菌种以及3种未鉴定的细菌菌种是从苍鹭的口腔上皮中分离出来的。在从食管采集的虫体表面未观察到有微生物附着。由于迟缓爱德华氏菌和聚团肠杆菌是从苍鹭食管中分离出的仅有的菌种，因此苍鹭口腔中细菌与虫体的紧密关联可能特别归因于无色杆菌属。
